The principal object of this invention is to provide an extremelyflexible form of release and interlocking -Inechanism` for machines ofthis class which is capable of being constructed in av plurality of-forms adapted to the particular system with which the machine isv to beused.

Another object of the invention is to provide vmechanism so constructedthat a key in eachof a plurality of banks may operate means t0 permitrelease of the machine.

Still another object is to have the releasing mechanism arranged so thatit is necessary to.`depress -a key in each of several banks before themachine can bel released.

With these and incidental objects in view, the invention consists ofcertain novel features kof construction and combinations of parts, theessential elements of which are set forth .in appended claims and apreferred. form of embodiment of which is hereinafter described withreference to the drawings which acckmpany and form -part yof thisSpecification.

In general.

4In machines of the t pe to which this invention-is. adapted to beapplied there are usually a pluralit of banks of amount keys and aplurality of banks ,of control keys. f The control keys are for thepurpose of'controlling the selection and engagement of nthe varioustotalizers corresponding thereto -on adding and totalizing operations.

AThese machines are normally locked against operation and the usual,means for releasing the machines for operation is a motor bar which,upon its depression, releases the machine for o ration and also closesthe motor circuit i the machine is operated byI an electric motor.

The release mechanismy which exemplifles this invention may be used in'any one of al lar e, number `of diilerent forms of whichA this mechanismis capable, depending upon the system with which the machine'is to beused. For instance, a com- -moneform of the release mechanism is thatinwhich it is controlled by three banks of control keys and a motor bar.

of afkey in each of the three banks is neces.

Depression sarybefore the machine can be released by the motor bar.

Another form which isshown herein i.P that in which keys in ,the firstand second gbanks of control keys must be depressed before the machinecan be released and a key mayor may not be depressed in the third bank,`an desired. c v

Still a different form is one in which the depression Of a key inA anyyof the. three' banks of control keys will`\un1ock and release themachine in conjunction with the motor bare These forms above noted, andwhich will be hereinafter described, are taken simply as representativeexamples of some of the various uses to which the novel mechanism mayybe ut. However, the invention is capable o being adapted for use in agreat many other combinations, which it is thought unnecessary to showand describe herein, without in any way' departing from the spiritthereof, and it is not desired to limit the invention in any wayto thethree forms of mechanism shown herein.

y Release shaft. In all machines of this type there is a re lease shaftwhich is adapted to be rocked in a clockwise direction (Fig. 6) by meansof a powerful s rin 26, which 1s compressed between a` air o members 27carried by a stud 28 pro]ecting through a slot 29 in a link 30, and ashoulder formed in said slot. The stud 28 is carried by an arm 31 faston the release shaft. In the normal position of the arts the releaseshaft is prevented from being rocked under the influence of the spring26 by the engagement of a halfround stud 32 (Fi 8) carried by an arm 33pinned to the s aft 25, with a pair of pawls 34 and 35 (Figs. 1, 7 and9) loosely mounted on a shaft 36 supported by the machine side frames37. It can be seen from Fig.-8 that so long as the pawls 34 and 35remain in alinement with the fiat face of the half-round stud 32 theshaft 25 cannot be rocked clockwise by the spring 26 to release themachine. When the machine is released, as will be hereinafter described,the releasing movement of the shafte 25 is limited b the engagement of aprdjection4 38 (Fig. 6 of the arm 31 with a pin 39 carried by the righthand side frame 37.

Rezeeee by meter ber.

When the proper keys in the keyboard have been de ressed the machine isadapted tobe release by a motor bar (Fig. 2), the shank of which has abiurcated end 46 ada ted ,to surround a pairof studs 47 carri by a plate48 which in turn is slidably mounted on a pair of studs 49 and 50,supported in. the right hand side frame 37, omitted from Fig 2, butshown in Fig 1. The plate 48 also carries a in 51 which c'o` o rateswith the bifurcate end of one arm o alever 52 which is pivoted on a studin the right hand side frame 37 (Fig. 1). At its o posite end the lever52 carries a pin 53 w of an arm w54 loose on the shaft 36. The arm 54 ismade integral with a hook member 55 .by means of a yoke 56. When themotor bar 45 is pressed in, the hook memich projects through thebifurcated endl A pin 57 (Figs. 1 and 2) carried by an arm 58 is adaptedto cooperate with the inner periphery of the hook member 55 and the arm58 will thereby be rocked clockwise upon the clockwise movement of thehook member 55. Integral with the arm 58 is a ment with the stud 32 uponthe depression of said keys in a manner which will be hereinafterdescribed. Therefore when the arm 58, yoke 60 and arm 59 are rockedclockwise it can be seen from Fig. 8 that the pawl 34 will be rockedcounter clockwise about the shaft 36 and will thereby become disengagedfrom the stud 32. rAs soon as both of the awls 34 and 35 are raised outof the path ci] the stud 32, this stud, together with the arm 33, shaft25 and arm 31 will be rocked clockwise under the infiuence of the spring26 far enough to permit operation of the cash register. The stud 32 willthen be positioned between the pawls 34 and 35 and another awl 62 looseon the shaft 36 and connected) to the pawl 34 by a spring 63.

Release by first control bank- Control by second and -tkz'nl banks.

The first of the three examples of the uses to which the presentinvention may be put will now be described. It contemplates mechanismenforcing depression of keys in all three control banks prior to arelease of the machine by the motor bar 45.

In order to prevent the release of the machine until a ke has beendepressed in the first, second an third control banks there are providedtwo members 68 and 69 fast on the shaft 25 (Figs. 1, 4 and 5). Thesemembers 68 and 69 have projectin portions 7() which normally lie beneathhoo s 71 and 72 loose on they shaft36. There are two of the hooks 71which cooperate with the mem-l the second control bank and the other bythe thirdbank. The hook 72 which cooperates with the member 69 is orated by the first control bank. Each of t e hooksv 7l and 72 isconnected by a yoke member 73 to an arm 74 also loose on the shaftf36.

control banks the detent appropriate to the contact with and rock thearm 74, and

lio

through arm 74 rock the yoke member 73 and 'hooks' 7l or 72,* dependingon which' bank ofi control keys has been operated,

` counter-clockwise about the shaft 36 far enough to remove the hookportions from above the projections of the members 69, which will permitthev machinel to be released. As there is one of these hooks 71 or 72appropriate to each bank of controlkeys in the example now beingdescribed, itcan be seen that it will be necessary` to depress af key ineach `of the threecontrol banks in order to permit the machine to bereleased. l

The yoke member 73 for the first bank of control keys has a downwardlyextending portionI which carries a pin 81 -projecting through abifurcated portion 82 lof a yoke member 83 loose` on the shaft 36.Integral with the left hand end (Fig. 1) of the yoke member 83 is thepawl 35 previously described, which cooperates with the halfround stud32 to normally prevent the release of the machine. It has beenpreviouslly described how the yoke 73 for the first lbank is rockedcounterclockwise (Fig. 5)

upon the depression of any of the keys of said bank," and, due to theconnection of theh pin 81 with the bifurcated portion 82 of the yoke 83this yoke and its corresponding pawl 35 will be rocked counter-clockwisefar enough to disengage the pawl from the halfround stud 32 and therebyrelease the machine in so far as the control keys are concerned.

For the purpose of compelling depression of control keys beforedepression of the motor bar can release the machine, the pawl 35is made`slightly longer than the pawl 34, so that the motor bar will not remaindepressed unless a control key has been previouslydepressed. The pointof the pawl 35 which'is operated from the control keys, is chamfered, sothat the pawl may move back into the path of the stud pin 32, when adepressed control key is released manually, as for example, when the[wrong control key has been depressed. This makes it necessary to have acontrol key in depressed position at the time the machine is releasedwhether the key is depressed prior or subsequently Yto or simultaneouslywith the release key.

Release bjz/ first bank-Control b z/ second lbmls--Depresszon of key` nthird bank scribed herein, in which'the invention may be used, will nowbe described. In this form it is desired to-have the de ression of thekeys in the third lcontrol ban optional with the operator. A depressionof4 a key in the second vcontrol. bank is required to permit the releaseof the machine and the depression -of a key in the first control bank isnecessary not only to permit the release ofthe machine but to partiallyoperatesthe .release mechanism, as was described in' connection with thefirst example. The mechanism 'which is adapted to produce the resultsabove mentioned is shown in Fig. 7, and it cann be seen by looking atthis figure that the mechanism is substantially the same as that shownin Fig. l.. In. order to make the third control bank free, the hook 7l',yoke 73 and arm 74 for this bank are left out andl the member the pathof the pro'ection of member 68,`

thereby permitting t e release of the machine in so far as this bank isconcerned. Thedepression of a key in the lirs't transaction bankthereforewill, through the detent 75, rock the arm 74, yoke 73 and hook72 to remove this hookfrom the path of the projection TO of the member69. The rocking movement of the yoke 73 will be transmitted to the yoke83 by means of the pin 8-1 and the bifurcated-portion 82 and willthereby rock the'pawl 35 out of engagementwith the stud 32, which willrelease the machine in so far asthe first transaction bank is concerned.1f the motor bar 45 is then depressed the'pawl. 34 which also cooperateswith the. stud 32 will be rocked out of en- Release of 'machine bg/depression.. of a key lim n either the rst, second, or third controlbarils.

When it is desired to release the machine by depression of a key in thefirst, second o r third control banks the mechanism used 1s like thatshown in Fig. 9. Only the mechanism on shaft 36 has been shown 1n thisligure, as .the mechanism on the shaft 25 1s, with one exception,identical with that shown in Fig. 7 ,fand just above described. The maindifference between the mechanism shown in Fig. 9 and the mechanism shownin Figs. 1 and 7 is the fact that there 1s only one of the hook members71 show n in Fig. 9. This is the hook which 1s adapted to cooperate withthe member 68 shown in Fig.- 7, A long yoke member 85 is provided inthis construction, which con-l scribed. It can therefore be seen thattheY depression of a key in any of the three control banks will, throughthe detent appropriate thereto,` rock its corresponding arm 74counter-clockwise and through the yoke 85 rock the hook 71 out ofengage- Y ment with the portion 70 ofthe member 68, as above described.As the yoke 85 is connected to the yoke 83, it is evident that il theyoke 85 is rocked counter-clockwise the yoke'83 will also be rocked in alike direct-ion and the pawl 35 which is integral with the yoke 83 willbe rocked out 0f engagement with the stud 32 and thereby permit themachine to be released in so far as the control keys in all three banks`are concerned. The depression. of the motor bar will then rock the pawl34 out of contact with the stud 32 and permit the rotation of the shaftunder the influence of the spring 26, as above described.

Illechamlsm for dsengagz'ng hooks on totalz'zing operations.

When the machine herein disclosed is operated lto take either a total orsub-total from any of its totalizers, it is essential that all of thehooks 71 and 72 be rocked out of the path of the members 68 and 69 sothat the machine can be released when only one of the control keys hasbeen depressed. This function is accomplished in the following manner.Every` machine of this type isy provided with a pivoted plate 91 (Figs.1, 2 and 7) which is commonly known as the total lever plate. When it isdesired to take either totals or sub-totals from any of the totalizersit is necessary first to rock this plate either counterclockwise orclockwise, as seen in Fig. 2, and as is well known in the art to one ofa plurality of positions. The plate 91 has a slot 92 formed therein.into which projects a roller` 93 carried by an arm 94 fast on a shaft 95which is rotatably mounted in the differential supporting frames of themachine. Also fast on this shaft are two arms 96 and 97 (Figs. l and 4)which carry pins 98, the normal position of which is just below the endsof the two arms 99 which are loose on the shaft 36. There is one ofthese'arms V99 for the rst bank of control keys (Fi 1) and another ofsaid amis winch is a pted to Cooperate with both the second and thirdbanks of control keys. 'The arms 99,carry pins 100 (Figls. 4, 7 and 9)which lie directly back of t e hooks 71 and 72, above lescribed.

From the above description it is evident that when the total lever ismoved to any of its totalizin or sub-totalizing positions the plate 91wlll be rocked either counterclockwise or clockwise, and due to the con.formation of the slot 92 the pin 93 which cooperates `therewith will berocked upwardly. As this pin 93 is carried by the arm 94 this arm andthe shaft 95 will be rocked clockwise (Fig. 2). The arms 97 being faston the shaft 95 will also be rocked clockwise (Fig. 4), which movementwill bring the pins 98 into contact with the lower ends of the arms 99and will thereby rock these arms counter-clock wise about the shaft 36(Fig. 4). As the aims 99 carry the pins 100 these pins will engage withthe hooks 71 and 72 and will rock -these hooks counter-clockwise farenough to remove them from the path of movement of the portions 70 ofthemembers G8 and 69 and through the yoke member 83 and the movement ofshaft 95, just described, the pawl will be raised out of engagement withstud 32 and thereby permith the release of the machine in the man- 11erabove described. i

It is obvious that the motor bar and lits pawl 34 may'be omitted and thefirst bank employed as a release bank. In this case one of the keys inthe first bank would be employed to release the machine for enteringamounts on, or takin amounts from, totalizers corresponding to eys inthe other contr/ol banks. This construction of the release bank is shownin the application refcrred to.

Interlocka.

A11 interlock is provided to prevent release of the machine if any ofthe control keys are only partially depressed or to prevent depressionof any of the control keys after the machine has been released. Thismechanism will now bev described.

Cooperating with each bank of control keys is a detent 101 which hasbeveled portions 102 which cooperate with pins 103 carried by each ofthe control keys (Figs. 2 and 3). It is evident from Fig. 3 that when acontrol key is depressed its pin 103 will move the detent 101 downwardlyuntil the pin 103 passes the beveled portion 102 of scifi detent.whereupon the detent will be returned to its normal position, as shown Ul; IIL' depressed keys in their depressed positions. The detent 101 issupported by an arm 110 which carries a pin 104 projecting through abi.urcat^d portion 105 0f an arm 106 loose on the shaft 36. The arm,

moana 106 carries a a key is partially depressed and the detent 101 ismoved downwardly thereby, will be raised `into the path of an arm 108fast on the shaft 25, which is the release shaft. I t can therefore beseen that when one of the control keys is depressed only part way thearm .106 will be rockedv counter-clockwise by the pin 104 to a positionin which the portionv 107 will obstruct the movement ofthe arm 108,which will therefore prevent the release of the machine while the Apartsremain in this osition. If the key is fully depressed, owever, thedetent 101 returns to its normal position, as shown in Fig. 3 and theportion 107 of arm 106 is rocked clockwise out of the path of the arm108 and thereforel there vwill be no obstruction to the movement of thisarm and the releasing movement of shaft 25 can take place. There is oneof the arms 106, together with its corresponding arm 108, cooperatingwith each bank of control keys. See Fig.` 1.

It is also apparent from Fig. 3 that when v the machine is released andthe shaft 25 rocked clockwise, the arm 108 will also be rocked into thepath of the portion 107 of arm y106 and therefore it will be impossibleto depress any oft the control keys as the detent 101 will be lockedagainst movement until such time as the shaft 25 is restored to itsnormal position.

The detent 101 is moved downwardly tol release the keys by engagement ofan arm 109 with'the horizontal portion of arm` 110 upn restoringmovement of shaftA 25 to w 'ch it is secured. The arms 109 and 108 maybe integrally formed, as shown.
